RADIATOR.

' Specification f Letters Patent Patented May ,5, 1914.

Application filed July 25, 1913. Serial No. 781,101.

To all whom it may concern:

Be it known that I, THOMAS HENRY HARRIS, residing at Birmingham, England, have invented certain new and useful Imrovements in Radiators; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in connection with radiators, condensers, coolers and the like apparatus, and has more specific reference to the attachments ofthe radiator elements to tanks or vessels at top and bottom. These radiator elements, hereinafter referred'to as elements, are cooling elements when the radiator is used to decrease the temperature, and areheating elements when the radiator is used to in-' crease the temperature.

It has been found necessary to have elements constituting the cooling part of radiators or condensers arranged so as tobe ca.- pable of detachment and replacement and to have elements individually independent ofeaoh other, so as to facilitate the building up of radiators according to the varying types of models used.

In constructing a radiator according to this invention I have been endeavoring to meet the requirements of motor car manufacturers, who prefer to have patterns differing from their competitors, and it is with the object of providing means for joining elements of various patteriis to the radiator tanks in a manner that allows said elements to be detachable from the upper and lower tanks, that I have made the following improvements. In formingor grouping the elements the upper and lower ends are .provided with a hood or cross pipe, which may be formed out of the element itself, or from separate pieces of metal soldered or brazed to the side thereof.

I- will-now proceed to describe this invention more particularly by reference to the accompanying drawings in which Figure 1 is a part sectional elevation of the upper part of an element, showing its connection with the tank. Fig. 2 is a back view of Fig. 1. Fig. 3 shows in section a modified form of connector employed for securing communication between the elements and top and bottom tanks. Fig. 4 is a back elevation of Fig. 3. Fig. 5 shows details of the construction illustrated in Fig. 1.

element A isconstructed in the usual manner from sheet metal. In forming the elements, the upper and lower ends ofsame may be slightly bell mouthed, and joined singly or in groups to a header, hood or cross pipe 3. Into this header or hood, whose function is that of a distributingpipe, an elbow 4 is soldered or otherwise secured at both topand bottom. Said elbow is preferably formed by stamping and in two parts 4 and 4 as shown in Fig. 5. Thus each elbow may carry one or two elements as shown in Fig. 4, or three or more elements as shown in Fig. 2. Within such elbows are secured perforated thimbles 5, engaging suitably spaced corresponding thimbles or cones 5 secured within the tanks B and C, asshown in Figs; 1 and 3, The cones or junction-pieces 5 .fit tightlyin holes in the tanks and are soldered tothem or otherwise.

bear against the elbow-pipes so that the thimbles 5 are'drawn tightly against the cones and the packing-Washers. The radiator elements A are tubular and of any approved construction. \Vhen the radiator is used on a motor car they are cooling, elements, and when't-he radiator is usedto heat a dwelling they. are heating elements. In Fig. 3, modificat ons of these connectors are shown. In Fig. 3, no thimble parse is employed within theelbow 4;, the latter, being 1n one piece, is coned to engage a corresponding part of the thnnble 5 The comcal ortions which en a 'e' with the 'unction pieces 5" are marked 12 in all'placeswhere shown in the drawings.

In Fig. details of construction are shown, the elbow 4, being stamped out of sheet metal in two parts t and st", these parts being soldered together by dipping. By these means the elements are secured to the tanks for water circulation. g

The operation is as follows: The elements A attached to elbows 4 are secured to the top and bottom tanks B and by means of screws 7 and are thus easily detachable for renewal or other purposes. By these means an effective joint is obtained for fitting any type of radiator body 10 with a plurality of detachable and replaceable elements.

I claim 1. In a radiator, the combination, with a tank, and a hollow junction-piece secured thereto and communicating therewith; of a removable radiator element provided with a hood, an elbow-pipe secured to the said hood and provided with a conical portion which communicates with the radiator ele" ment and engages with the outer end portion of the junction-piece, and a fastening bolt passing through the elbow-pipe and its thimble portion and screwed into the endoof the junction-piece.

2. In a radiator, the combination, with a noeamo tamr, and a hollow junction-piece secured o thereto and communicating therewith; of a removable radiator element provided with a hood, an elbow-pipe formed of two sections which are secured together and conneoted to the said hood, a hollow thimble engaging with and communicating with the elbow-pipe and provided with a conical portion which engages with the outer end portionot' the junction-piece, and. a fastening bolt passing through the elbow-pipe and the thimble and screwed into the end of the junction-piece.

In testimony whereof I have aflixed my signature, in presence of two witnesses. THOMAS HENRY HARRIS.
